About

I'm Rajat. I build things end to end. Engineering is the backbone, but I care equally about product thinking, design, and making technology feel right for people.

I started out in open source, contributing to Mozilla's ssh-scan as part of Mozilla Winter of Security. Building a security tool in the open sharpened my eye for correctness in code that matters.

From there I joined Arcesium, D.E. Shaw's technology spinoff, building reconciliation systems for financial data. Precision wasn't optional. That environment taught me how to think about correctness at every layer.

Around the same time, I took my first real swing at a product of my own, co-founding a fitness-tech startup called Vibranium. It taught me to ship fast and learn from real users.

Then I moved to Singapore and joined Gojek, the region's super-app, building communications and consumer platform products. That stretch taught me what it means to build at scale for millions of users.

I stepped away briefly to lead engineering at Vedantu, helping scale its live education platform through the COVID period, then returned to Gojek, by then part of GoTo Group, for a longer run owning the mobility core, from the consumer booking experience to personalization as a growth lever.

Through much of this, I kept teaching, running a bootcamp called CodeAsylums with hands-on workshops for students of all backgrounds, from school to college, teaching them different CS technologies and how to build things. The builder-plus-teacher instinct has always been there.

Every team I joined gave me a different lens. Scale, reliability, user empathy. I carry all of them now.

Today I'm at Aampe, building the learning and data engineering systems that power per-user AI agents. Our customers include Deezer, Swiggy, and Blinkist.
